A Gamma-Ray Burst (GRB) is a highly energetic explosion observed in distant galaxies, characterized by the release of intense gamma radiation. These bursts are among the brightest events in the universe and can last from milliseconds to several minutes. GRBs are believed to occur during the collapse of massive stars or the merger of neutron stars, leading to the formation of a black hole. Scientists study GRBs to understand the processes of stellar evolution and the conditions of the early universe. The detection of GRBs has been made possible by space-based observatories like NASA's Swift and Fermi Gamma-ray Space Telescope, which monitor the sky for these fleeting events.
